Provide Description

Throughout the framework of the EICROC challenge (growth and characterization of a big measurement ASIC, 32×32 channels, devoted to the readout of AC-LGAD sensors), the analysis exercise of the post-doctorant focuses on a technical contribution to the worldwide ePIC (electron Proton-Ion Collider experiment) collaboration related to the development of the long run Electron-Ion collider (EIC : Electron Ion Collider, New York, United States). The profitable candidate will work inside the “JLab-EIC” hadronic physics group of the “Excessive Vitality Physics” (PHE) pole of the Laboratoire de Physique des 2 Infinis Irène Joliot-Curie (IJCLab) below the supervision of Dominique Marchand, scientific coordinator of the EICROC challenge involving researchers (2), engineers (2) and technicians from IJCLab, OMEGA (Group for Superior Basic Micro-Electronics, 4 folks), from the division of electronics, detectors and computing for physics (DEDIP, 1 individual) of the CEA-Saclay/Irfu and Brookhaven Nationwide Laboratory (BNL, New York).

The work will consist in contributing to the event and the characterization of iterations of ASICs devoted to the readout of AC-LGAD kind sensors, able to superb timing (~30 ps) and spatial (~20 um) resolutions, which will likely be exploited by a number of detectors within the ePIC experiment, notably the Romans Pots. The employed researcher will work inside a collaborative setting and could also be required to take part within the supervision of PhD or Grasp college students.

The recruited individual will exploit the prevailing check bench developed for the EICROC0 protype (4×4 channels) to characterize the digital response of every channel, to judge the jitter, the crosstalk and to find out the cost sharing ratio of the system (EICROC0+AC -LGAD) through the use of a Beta supply and an infrared laser check bench. Script growth in Python will likely be vital to regulate ASIC parameters, to automate knowledge assortment and to file knowledge for evaluation. The profitable candidate may additionally be concerned in simulation work (GEANT4). The outcomes obtained would be the topic of progress stories (shows, stories) supposed for the EICROC worldwide collaboration and dissemination of the outcomes among the many ePIC collaboration. These actions may even be introduced in devoted worldwide workshops/conferences and, relying on the progress of the work, will end in publication.

The Laboratoire de Physique des 2 Infinis Irène Joliot-Curie (IJCLab, ) is a combined analysis unit below the governance of the CNRS, the College Paris-Saclay and the College Paris Cité. IJCLab is situated on the Orsay campus, 20 km south of Paris, accessible by RER B in 35 minutes.
IJCLab brings collectively about 700 folks and is organized into 7 scientific poles (nuclear physics, excessive power physics, astroparticles/astrophysics and cosmology, power and setting, physics for well being, accelerators).
The construction has very vital technical capacities (round 280 engineers and technicians) in all the main fields required to design, develop and implement the experimental gadgets vital for its scientific actions: mechanics, electronics, IT, instrumentation, expertise. acceleration and methods for biology. These technical strengths symbolize a key asset for the design, growth and the usage of the mandatory devices (accelerators and detectors). The presence of analysis infrastructures and technological platforms gathered on the laboratory web site can also be a significant asset. Lastly, round 90 engineers and technicians from administrative and help departments work alongside with scientists and technical personnal.
The chosen individual will be part of the JLab-EIC group which incorporates round 15 individuals (6 CNRS researchers, doctoral and post-doctoral college students). The Jlab-EIC group is a part of the excessive power physics (PHE) pole which accounts for about hundred members.
